  • Identifying Fall-Protection training needs for residential roofing subcontractors
    Applied ergonomics, 2012
    Co-Authors: Yu-hsiu Hung, Woodrow W. Winchester, Tonya L. Smith-jackson, Brian M. Kleiner, Kari Babski-reeves, Thomas Mills
    Abstract:

    Abstract Falls remain the leading cause of injuries and fatalities in the small residential roofing industry and analogous investigations are underrepresented in the literature. To address this issue, Fall-Protection training needs were explored through 29 semi-structured interviews among residential roofing subcontractors with respect to recommendations for the design of Fall-Protection training. Content analysis using grounded theory was conducted to analyze participants’ responses. Results of the analysis revealed six themes related to the design of current Fall-Protection training: (1) barriers to safety training; (2) problems of formal safety-training programs; (3) recommendations for training implementation; (4) important areas for Fall-Protection training; (5) training delivery means; and (6) design features of training materials. Results of the study suggest the need for informal jobsite safety training to complement what had been covered in formalized safety training. This work also provides recommendations for the design of a more likely adopted Fall-Protection training program.

  • Fall Protection Training: Needs Analysis for Small Residential Roofing Subcontractors:
    Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2009
    Co-Authors: Yu-hsiu Hung, Woodrow W. Winchester, Tonya L. Smith-jackson, Brian M. Kleiner, Thomas Mills, Kari Babski-reeves
    Abstract:

    Falls remain the leading cause of injuries and fatalities in residential construction. Because of job-specific work conditions and environmental constraints, the various construction trades (e.g., roofing, siding, or framing) employ different safety standards and Fall-Protection training practices. The purpose of this study, therefore, was to explore the specific training needs and training preferences of small roofing subcontractors. A total of 20 roofing subcontractors participated in this study. A mixed methods approach, incorporating a survey and semi-structured interviews, was utilized. Results from this study revealed that an individual's job title (i.e., his or her role on the jobsite) and the employer's existing training methods were accurate predictors of the employee's preferred training methods. This study also suggests the need for improved Fall hazard awareness among roofing workers via training. Context-relevant methods and workers' preferred physical forms in receiving training were identified and found to be most effective for safety training and learning in the workplace. Language: en

  • a case study on automated safety compliance checking to assist Fall Protection design and planning in building information models
    Construction Management and Economics, 2013
    Co-Authors: Jurgen Melzner, Sijie Zhang, Jochen Teizer, Hansjoachim Bargstadt
    Abstract:

    Worldwide occupational safety statistics show that the construction industry in many countries experiences one of the highest accident rates of all industry sectors. Falls remain a major concern as they contribute to very serious injuries or even fatalities on construction projects around the world. Since the standards and rules for protective safety equipment vary by country, the growing numbers of internationally operating companies are in need of tools that allow ubiquitous understanding and planning of safety regardless of the country where they operate. The problem is examined using a customizable automatic safety rule-checking platform for building information models. The applied rule-based checking algorithms are designed to be add-ons to existing building information modelling (BIM) software and can check models for safety hazards early in the design and planning process. Once hazards have been identified preventative safety equipment can be designed, estimated, and included in the construction schedule before construction starts. A case study implements the safety rule-checking platform on a high-rise building project. Fall Protection regulations from both the USA and Germany are applied to the developed rule-checking platform. Visualization of the safety information further explains the differences in the results once country-specific safety-regulative standards are applied on the same building information model. The case study also indicates that the role of BIM in safety design and planning can effectively assist the traditional safety decision-making process for Fall Protection equipment.

  • Simulating Loads on a Roof Structure Caused by a Worker Falling from a Roof Edge
    Journal of Architectural Engineering, 2017
    Co-Authors: Daniel P. Hindman, Tonya L. Smith-jackson, Lori M. Koch, Justin C. Morris, Lance D. Shields
    Abstract:

    AbstractChanges in the Occupational Safety and Health Administration (OSHA) Fall-Protection guidelines for residential construction since late 2011 have required the use of Fall-Protection and Fall-arrest systems for workers past a certain height. Evaluation of Fall-arrest anchor capacity depends on placement within a structure and includes strength of connections, truss/rafter elements, and bracing. The purpose of this study was to explore the use of a displacement-rate test for evaluating the strength and stability of Fall-arrest anchors connected to truss assemblies as a supplement to currently used drop-test methods. A two-truss assembly with bracing was used for comparison. A range of displacement rates from 254 mm/min (10 in./min) to 381 mm/min (15 in./min) was recommended for evaluating the capacity of truss assemblies. A comparison of truss-assembly failures found similar results for the displacement-rate test and the drop test. The addition of the displacement-rate test can provide valuable infor...

  • Wood Truss Installation Loads Due to OSHA Fall Protection
    Structures Congress 2013, 2013
    Co-Authors: Daniel P. Hindman, L. M. Koch, J. Morris, Tonya L. Smith-jackson
    Abstract:

    Recent changes to the Fall Protection exemption for residential construction require that all workers at 6 feet above a lower level must have a net, guardrail system, or be attached to a personal Fall arrest system. The purpose of this paper is to examine the capacity of anchorages for personal Fall arrest systems on light-frame wood truss roofs. A novel lateral load testing device was used to load trusses out of plane. Both mono-slope queen post single trusses and two braced king post trusses were tested. Lateral loads of single trusses were approximately 10% of the capacity required for a personal Fall arrest system. Variable displacement rates greater than 25.4 cm/min produced similar maximum load and failure results to impact testing. Workers should never tie off to a single truss element. Further research is underway to develop suitable truss assemblies that can be used as anchorages.
